GLP-1 Receptor Agonists: Practical Considerations for Clinical Practice

Conclusions GLP-1RAs are recommended as a preferred add-on agent to existing metformin monotherapy, as first-line therapy if metformin is contraindicated or poorly tolerated, and for use in combination with other oral glucose-lowering agents or basal insulin. Shorter-acting GLP-1RAs (exenatide and liraglutide) offer improved coverage of postprandial hyperglycemia, while longer-acting GLP-1RA formulations (exenatide extended-release, dulaglutide, and albiglutide) further improve fasting plasma glucose, which can result in additional A1C lowering. Reductions in body weight and blood pressure appear similar among individual agents, and small increases in heart rate are of unknown clinical relevance. Gastrointestinal adverse events abate over time with continued treatment and are less frequent with longer-acting GLP-1RAs. Hypoglycemia incidence is low but increased when GLP-1RAs are used with insulin secretagogues or insulin. GLP-1RAs target multiple pathophysiologic mechanisms in patients with T2D and improve glycemic control, although there are some differences within this drug class that may be relevant in clinical practice. Therefore, selection of the most appropriate treatment for individual patients is important.
